n8n form node is not receiving data #23319
Description
Describe the problem/error/question
I am using the n8n form, after populate all data, and submit, the node is not receiving any data. Weird, because it doesn't throw any error message. Just like freezing.
I check the documentation in the chat n8n helper bot, i configure variables extra in my railways instance, redeploy, but nothing changed.
What is the error message (if any)?
